3. Circumference of regulation soccer balls have a mean of 69 cm with a standard deviation of 1.50 cm. Assume that the circumferences of soccer balls are approximately normally distributed. Calculate by hand using Standard Normal Table. Sketch and
shade area. Check in Stat Crunch
a. What is the percentage of regulation soccer balls has a circumference that is greater than 69.9 cm? Round to the
